C: CAUTION
Wear appropriate work clothing, including a cap, protective goggles and protective shoes when performing
any work.
Remove contamination including dirt and corrosion before removal, installation or disassembly.
Keep the disassembled parts in order and protect them from dust and dirt.
Do not place the oil pan with its inner side facing up until it is installed, to prevent intrusion of foreign matter
into the control valve body.
Before removal, installation or disassembly, be sure to clarify the failure. Avoid unnecessary removal, in-
stallation, disassembly and replacement.
When disassembling the case and other light alloy parts, use a plastic hammer to force it apart. Do not pry
apart with screwdrivers or other tools.
Vehicle components are extremely hot after driving. Be wary of receiving burns from heated parts.
Use SUBARU genuine CVTF and recommended grease. Do not mix CVTF, grease etc. of different grades
or manufacturers.
Be sure to tighten bolts and nuts to the specified torque.
Place lifts, shop jacks or rigid racks at specified locations.
Apply CVTF onto sliding or revolving surfaces before installation.
Apply CVTF onto the press-fitting surface of the part before press-fitting the part using a press.
Replace deformed or damaged snap rings with new parts.
Before installing O-rings or oil seals, apply sufficient amount of CVTF to avoid damage and deformation.
Be careful not to incorrectly install or fail to install O-rings, snap rings and other such parts.
Before securing a part on a vise, place cushioning material such as wood blocks, aluminum plate, or cloth
between the part and the vise.
Avoid damaging the mating surface of the case.
Before applying liquid gasket, completely remove the old liquid gasket.
After removing the sensors, breather hose and plugs, plug the holes to avoid foreign materials intruding as
necessary.
During disassembly or assembly, be sure to use nylon gloves or paper towels. Do not use cloth gloves or
waste cloth.
